V0 LATILIZER.

SPEGIFICATION forming part of Letters Patent No. 571,81 1, datedNovember 24, 1896.

Application filed March 20, 1893. Serial No. 466,813. (No model.)

To (LZ whom it nuty con/carm- Be it known that l, JAMES H. VALENTINE, acitizen of the United States, residing in Chatham, in the county ofMorris and State of New Jersey, have invented certain new and usefulImprovelnents in Volatilizers, of which the following is aspecification.

This invention relates to Volatilizers, vaporizers, and 'inhalers of theclass used for volatilizing drugs, oils, and medicainents forinhalation, fumigation, and like purposes, and ainls to provide improvedapparatus of this character.

Heretofore such devices have been constructed with a water-boiler,heating-lamp, lamp casing, and dru g containing Vessel. Several examplesof such apparatus are shown in niy prior United States paten ts, No.323,547, dated August 4, 1885, No. 374,720, dated December 13, 1887, andin my application for patent liled September 18, 1802, Serial No.iilhll.

According to my present invention I provide certain improvements in thefeatures of construction and operation of Volatilizers, which will behcreinafter set forth.

ln the accompanying drawings, Figure 1 is a Vertical und-section of anapparatus constructed according to the preferred form of niy invention.Fig. 2 shows a modified-form mouthpiece, and Fig. 3 a furtherinodification of the mouthpiece.

Referring to the drawings, let A indicate the boiler; B, the Shieldsupporting the latter; C, the lamp orsource of heat Within the Shield;D, the base of the Shield, on which the lamp rests; E, the neck leadingfrom the boiler; F, the drug-reservoir; G, a Sponge or other porousarticle therein for holding the drug to be Volatilized, and H thediseharge-head or mouthpiece through which the vapor is discharged.

The boiler A may be of any usual construction. That shown consists of aclosed Spherical Sheet-metal Vessel formed of cup-shaped halves a and b,united at the flange o, and the upper half having an internally-smoothor screW-threaded collar d.

The shield B is a Sheet-metal casing of the nsual cylindrical form,having perforated walls for the entrance and exit of air and opening' ffor the entrance of 'the lamp and the usual diverging base D. The boilersits Within the upper end of the shiel d, the fian ge c resting on thetop edge thereof- According to my invention the boiler A is preferably aclosed boiler, its only outlet being through the collar cl, and Iprovide a contracted neck E, entering this eollar, through the hollowinterior of which communication exists from the boiler to thedrug-reservoir F. Preferably the neck E is a short tubular niemberhaving lower sorew-threaded end g, fitting into the collar cl, and upperinternallyscrew-threaded end 71, for connection with the reservoir.Preferably it is constructed with a branch Lhavin g aninternally-screw-threaded end "i, corresponding in size to the end hland norinally closed by a cap J, upon the reinoval of which cap thereservoir can be connected to the branch 1 instead of to the upper end7L of the neck, in which case the cap J will be Screwed into the end hto close it. Then the reservoir is applied at the branch l, theVolatilizer can be utilized to direct the Vapors laterally or upw'ardlyor downwardly, as desired, which is convenient where the person inhalingis seat-ed beside the apparatus, when the latter is on a table, or whenthe person treated is reclining. In the usual use with the reservoir attop the boiler can be conveniently filled through the branch by simplyrelnoving the cap J. The collar (Z and lower end of the neck E arepreferably of the same size at their j unction as the screw-threadedportion of the upper end 71, of the neck, whereby when desired the neckcan be oinitted and the reser- Voir F applied directly to the boiler.

According to my in'ention I provide a reservoir or conipartlnent F indirect communication with the boiler A, and I provide within thisreservoir an absorbent or porous material, as the Sponge for holding thedrug to be Volatilized. The reservoir F is preferably a casingeonsisting of a body K of spun metal, having a throat j externallyscrew-threaded and engaging the neck E, froln which point the bodybulges outwardly and rises in hemispherical form, having a shoulder Z,above which is a Vertical circular fiange m, at the top of which themetal is bent inwardly and downwardly, forrning a lip n, projecting intothe interior of the reservoir. Across the lower part of the body is aguard L, preferably consisting of a series of cross-wires sol dered tothe lower part of the body. The sponge G is pressed into the body K,resting on the guard L thereof, passing slightly under the lip n, and'projecting at center above this lip. The lip serves to retain thesponge in position in the body and to direct inwardly onto the spon geany condensation which falls on the lip.

The remainder of the reservoir F need not essentially be employed; but Iprefer to provide some protecting or inclosing provision beyond thesponge which shall carry a monthpiece or discharge for the vapors. InFig. l this consists of a cover M, having a circular flange o, fittingover the fiange m of the body, a shoulder p, resting on the lip nthereof, and a dome-shaped top q, covering the sponge G, and from thecenter of which rises vertically a tube N, which slightly above thecover is bent and projccts angularly, its upper end having a fiaringflange 7', which constitutes the mouthpiece I'I and is preferablyprotected by a screen or perforated guard 8.

I preferably provide an au'xiliary monthpiece o1' discharge II', (shownin Fig. 2,) in which the cover (here lettered M') for the reservoir isconstructed with a dome-shaped screen-cup 8', which rests on the body Kdirectly over the Sponge G.

Fig. 3 shows vanother inodification of the mouthpiece or dischargeespecially designed for use when the apparatus is employed as a perfumeror deodorizer. In this attachment the cover (lettered M2) for the body Khas a contracted neck P and a flaring month Q, across which is fixed afiat screen 82, the whole constituting the discharge or mouthpicce,lettered 1-12.)

In operation the rescrvoir will be applied to the boiler or to the neck,as desired, the boiler being first supplied with water and the lamplighted. The drug to be used will be supplied to the Sponge and thelatter forced into the reservoir. The cover M, M', or M2 will be appliedto the reservoir as circumstances dictate. Then as the steam or vaporrises from the boiler it will penetrate the sponge G and volatilize thedrug contained therein, and the products will be discharged through themouthpiece. Any condensation on the cover will fiow down the walls ontothe lip n and back into the sponge.

It will be seen that the invention provides an improved apparatus whichcan be conveniently and effectively used as a volatilizer, vaporizer, orinhaler for reducing drugs and oils to a gaseous state for purposes ofmedicinal deodorizing and disinfecting uses, and it will be understoodthat the invention is not limited to the eX-act details of constructiondescribed and shown as its preferred form. but that these can bemodified to some eX- tent without departing from the essential featuresof the invention.

The joints between the boiler, neck, reser- Voir, and its cover need notessentially be screw-threaded, as any other well-known joint will bewithin the scope of my invention.

Vhat I claim is, in volatilizers and analogous apparatus, thefollowing-defined novel features and combinations, substantially ash'ereinbefore set forth, namely:

In a volatilizer the boiler A and reservoir F in combination with theneck E connected to said boiler and having open end 7b and branch I forconnection with said reservoir` and the cap J closing the open ends ofsaid ;IAMES 1I. VALENTINI Titnessesr GEORGE H. FRASER, CHARLES K.FRAsER.
